A string is wrapped around a disk of mass m : 1.6 kg and radius R : 0.09 m. Starting from rest, you pull the string with a constant force F : 6 N along a nearly frictionless surface. At the instant when the center of the disk has moved a distance x = 0.11 rn, your hand has moved a distance of d = 0.32 rn. m F x F > d (a) At this instant, what is the speed of the center of mass of the disk? ch::mls (b) At this instant, how much rotational kinetic energy does the disk have relative to its center of mass? Kmt=:l
